single quote character

基本解释

Make sure that you specify the back-quote character (`) and not a single quote!
请确保使用的是反引号（`）而不是单引号。
If the value contains both a semicolon and a double-quote character, the value can be enclosed in single quotes.
如果该值同时包含分号和双引号字符，则该值可以用单引号括起来。
If the value contains both single-quote and double-quote characters, the quote character used to enclose the value must be doubled each time it occurs within the value.
如果该值同时包含单引号和双引号字符，则用于将值括起来的引号字符每次出现时，都必须成对出现。
